another thing I hope is worth mentioning after Simon so gloriously
solved my last problem in record time:
Now using Cabal 1.1.3, the permissions for globally installed packages
go wrong. Even though I used umask 0000 for these procedures, the
installed files had all no read permissons for no-roots. I think, this
problem was not there with the cabal version shipped with ghc 6.4.1.
